January 19th, 2015 Dual Impact Index presented by the National Collegiate Open

1/19/15 Dual Impact Index p/b @NCOWrestling

Here’s what the numbers all mean:

Individual rankings: The rankings are no longer being split into a win/loss ranking and a bonus ranking. Basically, all wrestlers set to 100 at the start of the calculation, and the opponents’ rankings having 30, 40, 50, or 60, depending on the type of victory (to correspond with dual scoring), either added or subtracted from it in each cycle. When the numbers stabilize to three digits (the one-thousandths place), the rankings are finalized for the week.
Eligibility standards are the same as last year. The rule is that each wrestler has to have had five matches against somebody else also in the rankings at that weight class. This means that all wrestlers will have at least five matches in the rankings to work with, reducing the numbers of outliers, and also means that a lot more redshirts and nonstarters (especially later in the season) will be included in the ranking. Wrestlers listed in red have not represented the team so far this year in either a dual or a single-entry tournament (so far, only the Cliff Keen Las Vegas Invitational, PSAC Championships, and Reno Tournament of Champions), wrestlers listed in yellow are either behind another wrestler at that weight or are instead ranked at another weight. If wrestlers would be listed at multiple weights, they are ranked at the weight in which they would be more beneficial to the team for a dual.
Team rankings have yet to debut, with the exception of the tournament-strength ranking, as I don’t think they would be overly significant at this point of the season with several teams without representatives at all weights.
Dual-Results:
Based on the results of duals themselves. Figured the same way as the individual rankings, with each team being given +/- 30 points for a win or a loss, plus or minus one point for each match the dual is won or lost by. Criteria points are not included in this figure.
Tournament-Strength:
Teams are given points on the same scale points are earned at the NCAA Championships, with bonus points.
Dual-Component:
Teams are matched up in mock duals based on how the individual wrestlers are rated. Bonus points are given at a margin of 17.5, 22.5, and 27.5 points, to simulate major decisions, technical falls, and falls, respectively. The number listed is the number of mock duals won.
Roster-Component:
Similar to the Dual-Component ranking, but includes redshirts. Basically, what things might look like if every single coach in the country pulled all of their wrestlers out of redshirt.
Columns:
WL: Based on only wins and losses
MOV: Based on only margin of victory/scoring of bonus points
SOS: Strength of Schedule
Total: Win/Loss plus MOV (Dual-Results only)
